Your first line of defense against illness is a robust immune system, and nutrition plays an important role in keeping yours strong. Because healthy superfood meals are packed with essential vitamins and minerals, they offer a great, natural way to enhance your immune response.
Here are ten superfoods you can add to your diet today to help naturally boost your immune system.
1. Blueberries
Rich in antioxidants (like anthocyanins, which give them their gorgeous deep blue color), blueberries are a fantastic source of vitamins C and K. They're also a great way to boost your fiber intake. They can help protect the function of immune cells, and better functioning cells are more efficient at attacking pathogens.
2. Spinach
Spinach is loaded with iron, calcium, and folate, as well as vitamins A, C, and E. This vegetable can help boost the production of white blood cells, which are crucial for fighting infections, so be sure to put spinach on your menu! It can also help maintain healthy mucous membranes and skin, the body's first line of defense against pathogens.
3. Garlic
Consuming garlic is a great way to boost your immune system, as it's rich in sulfur-containing compounds like allicin. Allicin can enhance immune function by stimulating the activity of immune cells. The antiviral and antibacterial properties of garlic also help prevent infections from happening in the first place!
4. Ginger
Ginger has a ton of anti-inflammatory and antioxidant properties that help bolster the body's immune system. By helping reduce chronic inflammation, which can weaken immune function over time, ginger can help you stay healthy.
5. Almonds
You probably know almonds are healthy for you but may not know why. They're an excellent source of vitamin E, a powerful antioxidant that protects your cells from damage by fighting off free radicals. They're also loaded with healthy fats that can help your body absorb fat-soluble vitamins, including vitamin E.
6. Turmeric
Like many other colorful plant-based foods, turmeric is rich in phytonutrients that may help shield cells from damage. The compounds within turmeric can also help the body fight any inflammation that wreaks havoc on immune function.
7. Citrus Fruits
What do grapefruits, lemons, oranges, and other citrus fruits have in common? They're all high in vitamin C, fiber, and antioxidants. These healthy powerhouses can boost the production of white blood cells, essential for fighting infections, and protect immune cells from damage.
8. Yogurt
Yogurt is rich in probiotics, which are beneficial for gut health. A balance of gut bacteria is a must-have for a strong immune system, as gut health is linked to a robust immune response. If you're looking to prevent harmful bacteria growth while supporting immune cell production, reach for the yogurt!
9. Green Tea
Sure, green tea has an amino acid that has a calming effect, but did you know it's also rich in catechins, a type of antioxidant? Catechins have been shown to enhance immune function by increasing the number of regulatory T cells, which help prevent autoimmune disease.
10. Sweet Potatoes
Not only are sweet potatoes delicious–they're a fantastic source of beta-carotene, which converts to vitamin A in the body. As vitamin A is crucial for maintaining healthy skin and mucous membranes, you can see just how beneficial it is to add sweet potatoes to your superfood meal plan.
